Now, apply all of the same techniques described in the comments here, on how to quit smoking, and apply them to Destiny, because it uses techniques and mechanics learned from lab rat studies on how to keep people playing a pos game. "I have been doing some serious digging, and have stumbled upon a article(http://www.gamasutra.com/view/feature/3085/behavioral_game_design.php) written in 2001 by Bungie's current head of User Research. John Hopson(Head of User Research) holds a Ph.D. in Behavioral and Brain Sciences from Duke University and is currently the chairman of the IGDA Games User Research SIG. Before he was hired by Bungie in 2002, John wrote an article explaining formulas to get gamers addicted to games, which many were based on lab mice experiments.

I would post each theory in its entirety on here but I feel like that violates the guidelines because its pretty much the whole article. If I can post it that way then let me know, but for now I will post each theory title in the article and summarize it for the lazy and relate it to the destiny formula.
